Cleaning high, hard-to-reach skylight gallery?

with our (Neigung 35 Grad) unfortunately it does not work with the robot

At 43 degrees DN, the window cleans itself from the outside. Inside, every few years is sufficient. If you also install a [Pliseemarkise] inside, the sun won’t bother you either.

We have an "unreachable window" from Roto at about 5m height. I always wanted to buy a suitable ladder for it (A-frame with extension). Well, how quickly nothing gets done. We have a telescopic pole and drip-clean ourselves at wide intervals. Due to the slope (27° in our case), the cleaning frequency remains within tolerable limits. Our tolerance limit for this dirty window is probably not standard, but 2-4 times a year should be enough depending on location and exposure for those who look a little more closely. The window is more practical than inconvenient. I would do it the same way again.

Now two questions have arisen:

I only have one question: why don’t you simply link to the plans of your probably still unborn and avoidable problem instead of many words?
